l Be it ylmown that 1,'GE0RGELW. LALLY, 'a citizen of thev United States, and resident of Boston, inthe county of Suffolk and State lof Massachusetts, have inventedan 'Improvement in Dumping Motor-Vehicles,

ofv which the lfollowing description, in oonneotioii 'with the accompanying drawings, 1s Va specification, like characters on' the dra'Wr ings'rcpresentin'g like parts.' f

My invention hides known as. dumping .cette lmiionly used in handling coal, bricks,fand ,other products which are y,con,veniently dumped or has., enforced the desirability of @using such vehles 'fr handling' 'Coal-,Q .but :this 11.66.63- sita'tes various C radical .changes in the' hoistfingv pparat'us suoli selfldumping auto- IriOlD'hJS..or motor'vehcle- .I 'Accordingly my presentinvention aims tofprovide a'- motor vehicle of thisr character Wi h` a hoisting or. I, dumping apparatus which, while exceedii'igl' powerful, ac-comi thel lim1'ted- 'space and sidewise g, manipulation made'jnecessary by the The .constructional details of m'y invention and the limitations Aoffthe['.ls'iltter,will more fully appear fromtlie following description, taken in connection with the accompanying drawings, in which I have shown a preferred embodimentfof the invention.

In the drawings, Figure i. elevation a vehicle provided with my. in-

mechanism,.said view being taken .approxi-h vent-ion; Fig. 2 is an4 enlarged fragmentary view in front elevation of the elevating mately on the line 2-2, Fig. 1; and Fig. 3 ine 7 is a cross-sectional view taken on the 3 3, Fig. 2.

' The veh`cle frame 1, seat 2, controlling apparatus 3, truck gearing 4, etc., are of any usual `or preferred kind. `Mounted on the frame 1 behind the upstanding seat 2 is a usual heavy box or load carrier '5 pivoted at coal and dumping the same when required. to the front of the box 5 and provided .withi a swivel connection for the lifting 'is'cijew 8, said connection consisting of a U- ,Sha ed casting. 9 pivotally mounted on a horizontal bolt -10 extending 'lengthwise of is` a vertical screwhoist vauto truck, andrela'tes tothat class o f ve-v;

1 shows 'in side Abracket( is securedl i 'the bex from the from' there@ and s1 nut 11 having threadedengagement with the screw 8 and pivoted atits ends 12' in the arms of the casting .9. This gives the. necessary freedom rof movement between? 'the'gscrew and thehbox `to accommodate thef'lat'ter 'in all its movements.` vAt ,its lower" eii'dthe screw 8 is provided Witfliday relatively large beveled ear meshing with a pinion 14 left side of the vehicle, where it isprovided with a handle 16I (usually removable) Thev Vscrew l8 and shaft' 15 are journalfed ina relatively heavy casting 17, the' `screw ylm )eing journaled yin an 'overhanging 'arm 18 of sai on a'sha tY 15 which extends laterally at the casting andthe shaft 1 5 independingfarms orf-connections' 194 wvliicliv 'efxtend v from Va relatively heavy base"20`. Said basehasI an arm 21 in whichthe lower endof `the 'shaft 58is loosely journaled,.said -lowe'nend at 22 beingprovided with. a 'conical recess 'itt-ing over a conical post 23which preferably: con

sists cfa s teelpiii cast' into the casting 20' to lproperly center and? givev a" firm Aend bearing -to the screw 8 to bear'the`fweightof`the latter and of the'load,fespecially"when the loadisbeing raised from ka 'horizontal'to an inclinedI position',l i. 'e.`ro'in 'thefullline u position to the. dotted-line positionQFizg. 1. On its under sidel thebase Ai's 'provided with lugs 24 pivoted on, pins 25 "i n ears 26 such apparatuses are apt to wear out. But

my construction largely obviates all this.

'By' havingan open space between the bear-` m 21 and the base 20 around the end of the screw shaft 8, if any grit vgets into this bearing, it simply works right through and drops out at said opening. The conical end bearing further facilitates the selfcleaning. B having the beveled gear 13 turned with its teeth on the under side and having the same large so that the pinion 14 is practically housed or sheltered be neath said gearing, all the teeth of the two gears are protected from the falling coal which would otherwise et into them when the vehicle is being loa ed. By providing l bearing.

a long bearing :for vthe shaft and mounting the latter as. close as possible to base` 20 Vof the casting, and by providing widely separated supports 26 for the opposite ends of said casting, great strength is secured without undue weight. Also by having the gear end of. the casting provided with a bearing adjacent its upper edge and 'panother at `its lextreme lower edge, it resists the strain to the best advantage which is brought upon it when the load is being raised to the dotted-line position. The weight of the load is moreover transmitted tothe various bearings one above the other in one and thesame vertical line.

I ydov not intend to limit the invention tol the precise structural details herein `shown in the preferred structure, as many changes may obviously be made Within the limits of the hereinafter expressed claims Without leparting from the spirit and scope of my invention. y Having described my invention, what I claim as new and desire to secure by Letters Patent, is: n

l, A'dumping `motor vehicle, comprising a'` pivctally mounted load carrier, an elevating screw havingtlireaded engagement with one end thereof, gearing for operating` said'scremand a pivoted bracket support'v for saidgearing and the lower end of said screw, said support having an upward projection to lit into a socket 1n the lower end of the screw to provide a grit-shedding 2. `A dumping inotor vehicle, comprising a pivotally mounted load carrier, an elevan ing screw having threaded engagement with one end thereof, a 'base mounted on transe verse pivots on the vehicle and carrying aplvot support for saldsnrew, driving 'means for said screw extending transversely the kind described, comprising a hoisting'- screw, a nut for communicating the motion thereof to the part to be hoisted, a supporting bracket for the lower end of the screw adapted to extend transverselyof the ve-4 hicleand provided on its under side with spaced apart pivotal bearings, a gear wheel carried by said screw, said bracket having two overhanging journal bearings for said screw,`one abovesaid `wheel and one below the same, and a pinion and pinion shaft journaled longitudinally of said bracket to extend laterally of the vehicle for operating said gear wheel and' screw, said bracket being provided with a conical end bearing p'in for the extremelower end of said screw, the overhanging lower'journal bearing of said bracket affording an open space about said pin and said extreme lower end of the screw to aid the lbearings in freeing themselves of rit. i

I testimony whereof, I have signed my name to this specification, in the presence of 'two subscribing witnesse GEORG-E W. LALLY. Witnesses:
